需求2:如果要替换的敏感词比较多怎么办?
```java
public class Test10多个敏感词替换 {
public static void main(String[] args) {
//实际开发中,敏感词会有很多很多
//1.先键盘录入要说的话
Scanner sc = new Scanner(System.in);
System.out.println("请输入要说的话");
String talk = sc.next();//后裔你玩什么啊,TMD,GDX,ctmd,ZZ
//2.定义一个数组用来存多个敏感词
String[] arr = {"TMD","GDX","ctmd","ZZ","lj","FW","nt"};
//3.把说的话中所有的敏感词都替换为***
for (int i = 0; i < arr.length; i++) {
//i 索引
//arr[i] 元素 --- 敏感词
talk = talk.replace(arr[i],"***");
}
//4.打印结果
System.out.println(talk);//后裔你玩什么啊,***,***,***,***
}
}
